I am using the STM32H743II package (with Vref+ and Vref-). Those two pins are not connected in this design (they're left floating). I'd like to measure the temperature of the chip, and am having trouble using the internal voltage reference as the ref...
Hi community,I'm currently trying to set/reset the BFB2 bit from application program, under MBed, with a STM32L476RG.Though setting/reseting BFB2 can be done properly thru ST-LINK, I did not manage in modifying the option bytes, using the HAL/LL driv...
Hello there,We are using your STM32F030K6T6TR MCUs extensively in our Fotokite systems. They communicate via I2C. We have different MCUs on different, isolated grounds and are therefore currently using the Si8602AC-B-IS I2C isolator. This device does...
I use stm32l496. before entering the low power run mode I set the output but when micro enter lprun the output is reset.I want to know what the status of the outputs is at low power mode?andcan the outputs be changed or read?thank's.
Is it possible with the 32F769IDISCOVERY board to access the CAN bus of the micro? I can't seem to manipulate STM32CubeMX's Pinout & Configuration to get CAN activated. Ideally, I'd like to drive the display, run LwIP over a fully active ethernet p...
Hello.I am currently developing with STM32L Discovery.In preparation for development, I tried to output using the MCO in order to know the exact frequency of the HSI of the evaluation board used.By operating MCOSEL in the RCC-> CFGR register, MSI and...
Hello,I have a doubt regarding DMA memory to peripheral ?Suppose I would like to transfer a memory buffer content to SPIx TX.When do each transfer occurs ? Every time I change the content of the memory buffer ? Always ?I cannot find this information...
Hi,When looking into stm32l4xx_hal_sd.c, I observed the following code: if(hsd->SdCard.CardType != CARD_SDHC_SDXC) { add *= 512U; } /* Set Block Size for Card */ errorstate = SDMMC_CmdBlockLength(hsd->Instance, BLOCKSIZE); if(errorsta...
I have a design where I am using both I2C1 (external ADC) and I2C2 (external EEPROM). I have no problem making I2C2 work perfectly. The MCU both transmits and receives messages with no problem and I can see in on the Oscilloscope. However, when I att...
We have the following situation: We want to use the FDCAN of the STM32H743ZI with 500 kbit/s. We've got followingconfiguration parameters for the FDCAN1:hfdcan1.Instance = FDCAN1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC; hfdcan1.Init.Mod...
